Pumice Stone (2–6mm) is a lightweight, natural volcanic rock that enhances soil structure by improving drainage, aeration, and long-term root health. Its porous surface retains moisture while allowing excess water to drain freely, making it especially effective in preventing overwatering in pots and planters.
This pre-washed pumice is ready to use and ideal for succulents, cacti, bonsai trees, and general houseplants. Unlike perlite, it won’t float to the surface or break down — making it a reliable, long-lasting amendment for your soil mixes.

Frequently Asked Questions
Is 2–6mm pumice the right size for succulents and bonsai?
Yes. This size provides the right balance of moisture retention and drainage, making it ideal for succulents, cacti, bonsai, and indoor plants.
Can I use pumice alone as a growing medium?
Not recommended. Pumice has no nutrients. It should be mixed with organic material like compost or potting soil for best results.
Will this pumice break down over time?
No — pumice is a volcanic mineral and stays stable in soil permanently. It doesn’t compact or degrade.
Does this pumice float like perlite?
No. It’s heavier and stays evenly distributed in soil, which helps maintain consistent root-zone conditions.
Do I need to rinse this pumice before use?
No. This pumice is pre-washed, dust-free, and ready to use straight out of the bag.
